This is a bug of the old rsvg.

Please, use the latest rsvg version in your tests and compare with chrome/firefox first.

I have Ubtuntu 18.04 LTS so it is default is rsvg-convert version 2.40.21, installing newer ones leaded to problems (depends on cairo 1.16,...)

I think I will wait till April for Ubuntu 20.04 LTS and then update

installing newer ones leaded to problems (depends on cairo 1.16,...)

Yes, I've also ran into this. Here is a workaround (edit paths and versions first):

cd cairo-src
./configure --prefix=/my_path/cairo-build-1.16
make 
make install
cd librsvg-src
env PKG_CONFIG_PATH=/my_path/cairo-build-1.16/lib/pkgconfig ./configure --prefix=/my_path/librsvg-build-2.47 --enable-introspection=no --disable-pixbuf-loader
make 
make install

my_path can be replaced with any user path like /home/name/ (do not use ~).

And that's it. No need to install anything as root.
